One day I'm going to open this thread and its going to be an announcement about being able to clear the brake errors... someday... maybe for christmas that dream will come true...

Here's your answer (unfortunately, not simple, as you need an additional tool, personally I'm hoping the GAP guys will find a solution)

Good evening everyone. I'd like to share an enlightening experience I had today while updating the settings on my Defender 110. This will sheds some light on why the GAP IID3 tool might encounter issues updating certain features, particularly Adaptive Cruise Control, Park Assist, and others. Additionally, it provides insights into the source of the Emergency Brake Assist Error.

I believe I might be echoing something discussed by a colleague in a previous post, so please pardon any repetition.

First and foremost, I extend a sincere thank you to Ralph and Sarek Auto in Virginia for their invaluable assistance in resolving this issue. Their expertise and unquestionable knowledge about the vehicle were instrumental. If you're interested in learning more about their work, you can visit https://www.sarekautowerke.com.

For context, I own a 2022 P400 Defender 110, and all features are functioning flawlessly after this update. Further confirmation may be required by conducting tests on additional models.

Now, let's dive into the good and not-so-good aspects of our GAP IID3 tool.

The positive news is that we've collectively identified the correct keys that need modification to activate the Adaptive Cruise Control and Park Assist.

Regrettably, the downside is that the current version of the GAP IID3 tool (4.2.2 Build 162) fails to communicate with the right ECU module to implement changes made through the app. Which is the Driver Assistance Domain Controller (DADC).

During our recent experience, we applied all the necessary changes via the GAP tool to enable Adaptive Cruise Control and Park Assist, uploaded the Car Configuration File (CCF) settings to the vehicle, and, as expected, encountered the Emergency Brake Assist Error immediately.

Following the changes with the GAP tool, we connected the Land Rover tool to the car, performing a single action—calibrating (rewriting) the Driver Assistance Domain Controller (DADC). This process took approximately 30 seconds, and upon the car reboot, the Emergency Brake Assist Error vanished, and all features operated correctly. https://www.lrdefender.org/speed_control_d...n-630.html

An important detail worth noting is that each car's CCF, linked to its VIN number, is stored on Land Rover's cloud. While the GAP IID tool changes the CCF locally, it doesn't update on Land Rover's cloud. If you ever need to reprogram your vehicle at the dealer, they might overwrite your local CCF with the version on their cloud, which would result on a redo of all activations. The only way to keep your changes permanently in your vehicle is uploading the new CCF to Land Rover's cloud, which apparently is only feasible with the manufacturer's tool.

In summary, we all have a remarkable and user-friendly tool that empowers us to perform various tasks, including local feature activations, error identification, real-time performance monitoring, and much more. On the other hand, as with any software, ongoing improvements are inevitable, and soon we might have the capability to write on the Driver Assistance Domain Controller (DADC) which will allow us to activate features like Adaptive Cruise Control and Park Assist.

I trust this experience helps Patrick and the team to identify the missing elements and opens doors for expanded functionalities.

Keys used for the activation.
Important: This will not work with the GAP IID3 tool (4.2.2 Build 162). The current version does not update the Driver Assistance Domain Controller (DADC), which can be updated using the dealer's version.
